EDITORIAL

continued from page 6

a 120-page monthly with over
100,000 circulation — almost before
we had time to stop keeping our
records on scraps of paper stuffed into
shoeboxes.

In many ways, 1984 was Antic's
most challenging year. The micro-
computer shakeout hit the market
hard. Suddenly many computer stores
wouldn't accept Atari products and a
number of our steadiest advertisers
went out of business. Some of the
best-est:iblished computer magazines
went under during 1984. Frankly,
there were computer business "ex-
perts" who wouldn't have been sur-
prised to see Antic call it quits too . . .

But the Antic staff is just too inno-
vative and dedicated to ever give in
to a downturn. We simply tightened
our belts and looked for more ways

to work smarter. And now we've
come through stronger than ever —
as the turnaround of the past few
months vindicated all those who
believed in the Auiri as the best 8-bit
personal computer ever made.

New subscriptions have been pour-
ing into Antic at the rate of nearly
1,000 a week. More and more third-
party manufacturers who'd turned
their backs on Atari are now coming
back to show their support in the
pages of this magazine. Even more im-
portant, Antic has lived up to the
pledge wc made to our readers last
autumn — to find new ways to fill the
vacuum in Atari information and
services. . .

You can now read full details of the
latest Atari news just hours after it hap-
pens, in the ANTIC ONLINE edition
on CompuServe. And in only a few
short months, the Antic Arcade

catalog has become one of the most
important outlets for top-quality Atari
books and software — including many
of the previously out-of-print APX
software classics.

These are only two of the new ser-
vices Antic began providing this year;
there's also the national directory of
authorized Atari service centers, the
Worldwide Users Group Network
(WUN). . .and more!

So the Antic Third Anniversary
arrives right in the middle of our most
productive and exciting period ever.
Thanks for coming along with us.
Antic will have even bigger and bet-
ter surprises for you during the rest
of 1985!

And you can bet that the best
coverage of the new Atari XE and ST
computer models will continue to be
found right here in these pages!

. . «and we won't take it anymore!

Dear Antic

Attached is a copy of the letter I sent
to Broderbund Software expressing
my disappointment in their decision
not to publish an Atari edition of
Cliampionship Loderunner.

I think all Atari owners should unite
and start writing letters to software
companies to let them know how
many of us are out there.

Timothy E Hitchings
Staten Island, NY

Mr. Timothy E Hitchings is absolutely
right . . . and Antic has received many
letters similar to the one above. It's
time for Atari owners to demand first-
class citizenship in the personal com-
puter software world!

Now is the time to take action, be-
cause there is no longer the slightest
excuse for major software companies
to avoid bringing out their hit prod-
ucts for the Atari.

Just about half a million Atari

BOOXLs were sold during the 1984
holiday season. In many stores, Atari
1050 disk drives moved out just as
fast — as previous owners upgraded to
disk.

Fahrenheit 451

Add this to nearly a million previ-
ously-sold compatible Atari com-
puters and you have a vast user base
that does not have to take second
place anywhere in the personal com-
puter market.

So when YOU see a piece of soft-
ware you'd like to buy, and you learn
it isn't being released for the Atari,

your next step should be to write a
letter to the president of the software
company explaining what a big mis-
take they are making.

You can usually find the company's
address on the software package or
on the advertisement for the product.
You don't need to look up the name
of the person who heads the com-
pany—just write PRESIDENT on the
envelope above the company name
and address. Feel free to enclose a
photocopy of this editorial along with
your letter, in order to add a second
voice to your argument.

On my desk at Antic as I write this,
there's a pile of superbly packaged
color-graphics adventure software
from Spinnaker — all for the Apple and
Commodore computers.

Spinnaker's Teralium line (origi-
nally called Trillium) features graphic
adventure software adapted from
famous science fiction books in-
cluding Ray Bradbury's Parenheit451,

MODIFICATIONS AND KUDOS
FOR TYPO II

Congratulations on your error checking
program, TYPO II. It is short, fast and a
great help in accurately typing your
listings.

Here are a couple of modifications. For
those of us with BASIC XL or an auto-
numbering program, typing in the line
numbers is not considered a life enriching
experience. The following changes let you
step through each program line by typing
an asterisk and [RETURN] .

Tliis causes each succeeding program
line to be listed and automatically
checked, making it possible to type the
program with an auto-numbering routine,
and then check it without ever typing in
a line number

Even if you don't use auto-numbering,
these changes will make it a lot pleasanter
for you to step through the lines of a
previously t>ped jirogram that you're
modif)'ing.

Line 32210 is changed to make the two-
letter codes appear in white, as they do
in the magazine.

I could get my Trak repaired by Electronic

BEATING THOSE
FOOTBALL BLUES

A February, 1985 I/O letter asked about
football handicapping programs. Several
football statistical and prediction programs
can be found in "BASIC Betting: the Micro-
computer Edge," by James Jasper ($9.95,
St. Martin's Press, NY). It covers baseball,
basketball, football, and horseracing. It
was intended for the Apple originally, but
it should be possible to rewrite these pro-
grams for the Atari.

SEARS MONITOR GHOST

When Antic reviewed the Sears $349.99
Proformance TV/Monitor in our

December 1985 Buyer's Guide, we wrote
that it had a distracting color ghost when
used as an At;iri monitor At the time, local
Sears spokesmen assured us that the prob-
lem was a unique glitch in the unit we had
borrowed for review.

As a result of monitoring the Compu-
Serve Atari SIG, Antic has now discovered

Is it possible to put a CPU expander bus

Greg Metallmos

We checked ivith Bill Wilkinson, who tells

TWO-FACED FLOPPIES

Can you notch a single-sided disk and use
the other side? If so, will it cause any
harm?

Ra)'mond Moody
Fort Ord, CA
/. Yes . . . Notching a disk is easy — you
can just use a regular hole punch. To he
sure of putting the notch in the right spot,
bold an already-notched disk behind the
disk you 're punching.

2. Possibly . . . You run a slight risk in
using the floppy sflip side. A disk drive's
read/write head presses the bottom of a
disk against a felt pad. Pieces of dirt or
metal could get stuck in the pad and
scratch the "A" side of your disk if you 're
recording on the second side. However,
at Antic we routinely use both sides of
disks all the time and haven 't lost any files
yet. It's up to you if you 're willing to take
even a tiny risk tvith your disk data.

CHIPS, CHIPS,

EVERYWHERE CHIPS

What can you tell me about the Western
Design Center's OXl-CMOS W65SC802
CPU or related chips? It is supposedly a
16-bit processor compatible with existing
6502 applications. The chip is compatible,
pin for pin, with the 6502 used in Ataris.
Mike Rutledge
El Segundo, CA
We checked with Charles Cheiry, of
Technical Support in Daly City, ivho sup-

plied the following information and
short history of the .Atari 6 502. -ANTIC ED

The Atari 400 and 800 use the 6502B, a
faster version of the original 6502 inicro-
processor The 6OOXL and 8()0XL use the
6502c, a substantially different chip that
incorporates support functions that, in the
days of the 6502A, were contained on
separate chips. A further consolidation of
support chips led to the 6510, which may
be used in the new XK C(jmputers.

There are three other interesting chips
in the 6502 family.

The 65C02 (a plug-in replacement in
the Atari 400 and 800) offers the increased
reliability, decreased power consumption
and heat generation, and better heat im-
munity of CMOS. It also has new machine
language instructions and addressing
modes, which are supported b)' the
MAC/65 assembler cartridge from O.S.S.

The other two chips are 8-bit and 16-bit
processors based on the 6502. The 8-bit
W65SC8()2 has new instructions and ad-
dressing modes. It appears to ha\'e the
same new capabilities as the 65C()2, and
may work with MAC/65.

The 16-bit W65SC8I6 chip probably
won't work with the Atari because of the
pin arrangement. Q

TSCOPE
AUTODIALER

Automatic los-on program

by CHARLES JACKSON, Antic Program Editor

TSCOPE, by Joe Miller is a well-
known public domain program. It
enables owners of the Atari 1030 or
835 modem — or most modems that
work with the Atari 850 interface —
to upload and download either binary
or ASCII files on the CompuServe SIG
Atari.

(TSCOPE is available on the An-
tic 1030/835 Telecommunications
Disk, PD025 in the Antic Catalog.
-ANTIC ED)

TSCOPE Autodialer is a fast and
foolproof way to log onto Compu-
Serve automatically. You just boot
your TSCOPE disk and sit back while
TSCOPE Autodialer types in your
CompuServe phone number, your
User ID and your password.

When TSCOPE starts, it looks for
a file named AUTODIAL.SYS which
contains a simple set of log-on in-
structions. AUTODIAL.SYS is optional
and doesn't come included with most
versions of the TSCOPE program. You
must create your own.

GETTING STARTED

TSCOPE Autodialer will create an

A short, iiiitoniiitic loi^-on /)n)i^ra}n
for TSCOPT. the l)o[>iilar public do-
main telvcoDiiniiniaitioiis l)rogmni.
It will run on any Atari coni/)utcr
tvith a disk drive. Works icilli any
TSCOPE compatible nnxlciii. in-
cluding the Atari I030 & 835.

AUTODIAL.SYS file for you. Type in
Listing 1, checking it with TYPO II,
and SAVE a copy to disk.

Wlien you RUN the program, it will
ask you for the phone number to dial,
your access number (User ID), and
your password. When you've entered
this information, place your TSCOPE
disk into the drive and press [START]
to write the file. If you haven't already
renamed your TSCOPE.OBJ file
AUTORUN.SYS, the program will re-
mind you to do so.

TSCOPE Autodialer creates an
AUTODIAL.SYS file which might look
something like:

555-1234

AC]:98765.4321

]: SECRET PASSWORD

The first line contains the phone
number to be dialed. Hyphens, paren-
theses and blank spaces are ignored
by TSCOPE.

The second line begins with A C —
the code for [CONTROL] [C], The
right-bracket symbol "]" after the "C"
stands for "wait". This tells the
autodialer to wait for a prompt before
continuing.

With our sample AUTODIAL.SYS
file, TSCOPE would dial 555-1234
(ignoring the hyphen) and wait for a
connection. Then your autodialer
would issue a [CONTROL] [C] code
and wait for the colon [:] at the end
of the User ID: prompt. When the
autodialer receives this colon, it enters
your access number.

The colon on the last line of the
AUTODIAL.SYS file tells the
autodialer to wait for the next
colon — the one at the end of the
Password: prompt. It then enters your
password.

MAKING CHANGES

There are many ways to modify your
autodialer. If you wanted to
automatically visit the ANTIC
ONLINE service, for instance, you
would add this line to your
AUTODIAL.SYS file:

a]!GO ANTIC

This instruction tells the autodialer to
wait for an exclamation point prompt,
then type the GO ANTIC command.

PASSWORD PROTECTION

Though TSCOPE Autodialer is the
quickest way to log-on to Com-
puServe, it lacks some security.
Anyone who can load a disk and turn
on a modem could gain access to your
CompuServe account. So always keep
your autodialing TSCOPE disk in a
safe place. Listing on pase 80.

In April, type GO AN'l'IC as soon as
you log onto CompuSciTe. You'll be

Book of Adventure Games

by Kim Schuette

$19.95

344 pages, paperbound

Cheating is expensive. In this case, it
will cost you about $20 to obtain
maps and cheat sheets for most ex-
isting adventure games.

Of course, it might well be worth
$20 to avoid those sleepless hours, as
you pull out your hair and wonder
how to get past that bear or enter
those massive doors in your favorite
adventure game.

Whether you want to use such a
cheat book is your business. But if you
do, you'll find this an excellent guide.

Maps and solutions reflect actual
gaming experience and include ap-
propriate editorial comments. The
maps are well drawn and clearly
presented. However, in our random
sampling of game clues, some maps
contained minor, but frustrating in-
accuracies. Clues are provided as
needed, in the form of numbered
notes. These clues are in a separate
section at the end of the book, so it
is possible to just peek at that one
answer you absolutely cannot figure
out.

Each game also comes with
publisher information, suggested
retail price, description and brief
review, necessary menus and
character charts.

The Book of Adventure Games
covers over 75 titles, most of which
were designed for the Apple. But 42
are available for the Atari, including
all Infocoms except the very latest, the
Ultima series, the Adventure Inter-
national catalog, Gruds in Space,
Ulysses, Wizard and the Princess, and
most other favorites.

Atari Graphics and
Arcade Game Design

Atari Graphics & Arcade Game
Design was written for intermediate
BASIC programmers ready to master
the Atari at a higher level.

This is not a book for beginners
who think a "Sprite" is something that
goes well with a hot dog and a
"redefined character" is a fellow
who's had a spiritual experience.

The early chapters deal with
display lists, character set graphics and
ANTIC and GTIA gi-iphics modes.
Several short BASIC program listings
are included to illustrate key points in
the text.

In a gentle introduction to
Assembly Language, a BASIC version
of a "Breakout " game is taken apart
and its subroutines are explained. En-
suing chapters compare each sub-
routine to equivalent assembly lan-
guage macros. By the time you're
through, you should be a lot closer
to designing and writing your own
machine language arcade games.

Although the assembler listings are
written in S)'nassembler, the book has
a comparison table to help you trans-
late the Synassembler code to Atari
Assembler Editor, MAC/65, Atari
Macro Assembler or Eastern House.

If you're a beginning programmer,
you'll want to keep your BASIC
reference manual close at hand, since
the workbook only describes BASIC
graphics commands.

Each workbook chapter introduces
a different style of computer graphics,
including high, low and medium
resolution modes; single and multi-
color modes; the GTIA modes and
three text modes.

The book contains many illustra-
tions and dozens of short type-in pro-

This Logo tutorial simultaneously

Several of these designs are presented
in an eight-page color section in the
middle of the book.

The authors invite you to use their
book like an encyclopedia — to "flip

the first of that insanely funny series
of books by British author and ex-

found the solution was logical and
often accompanied by previous clues.

In fact, if you stumble around
enough in certain problem areas, the
computer will eventually throw in a
hint.

The best way to understand this
British whimsy is to read and enjoy
Adams' books or possibly the works
of Lewis Carroll.

This extraordinary game is the
result of an unusual partnership.

Adams, who is a long-time fan of Info-
com games, approached the company
with the possibility of doing a game
based on his book. He teamed up
with Steven Meretzky, the award-
winning author of Infocom's
Sorcerer and Planetfall.

The result is a step forward from
Infocom's safe, established approach
to game design. It is a break from the
tradition of event-specific mysteries
and plotless underground dungeons.
The style of writing is distinct and
tangible — really the first stylistic
departure since the classic Zork
trilogy.

Tips for novices: play the game
with a grizzled Infocom adventurer
OR a crazed Hitchhikers fan.

And now, we now have a confes-
sion to make. We had planned on get-
ting this review into print at least a
month ago, but we hoped to finish the
game first. Alas, we simply haven't
been able to get past the Screening
Door So, if anyone out there has a
clue. . .

GEM of
ATARI

More than pretty icons/

mmm*mt

mmm*m*

«■)««■■

hen Jack Tramiel an-
nounced that the new
l6-bit STs would use the
GEM operating environ-
ment, he joined Atari to one of the
most innovative lines of research in
computer history.

During the 1970s a group of digital
visionaries gathered at Xerox's Palo
Alto Research Center (PARC) to ex-
plore how computers should relate to
people. They wanted to teach "people
literacy" to computers instead of com-
puter literacy to people.

It is already hard to remember how
difficult it used to be to operate com-
puters. You literally needed a com-
puter science degree to use them. But
video screens and electronic key-

boards replaced punch cards and
teletypewriters in the '70s. And in
those new video terminals, the PARC
dreamers saw the future ... A video
screen could show anything, and a
picture could replace a thousand
words.

IDEA PICTURES

The icon was born, a picture of an
idea. Like international traffic signs,
an icon can communicate more
quickly and more vividly than words.
A file cabinet represents a database, a
piece of paper stands for a word pro-
cessor, a disk means DOS. Since icons
can be small and simple, many can be
put on the screen without confusion.
You can see all of the available options

simulaneously. All you need to do is
select among them.

But how do you select an icon? The
gang at PARC tried everything, key-
boards, touch tablets, light pens,
joysticks and finally a mouse. The
mouse was their choice — simple,
natural and intuitive.

There was one more element to in-
vent, a visual metaphor for the way
you use a program. As you do various
things in a program the entire screen
keeps changing. For instance, if you
want to change the skill level of the
game you are playing, the playfield
disappears and the option screen ap-
pears.

But the PARC researchers thought
this was wrong. You should not have
to jump around in a program, the pro-
gram should come to you. Hence the
idea of windows. A portion of the
playfield would open up and reveal
enough information for you to make
your choice, while the rest of the
game is still visible behind the
choices.

PARC TO MAC

These visions led Xerox to build the
dream machine called Star It was
wonderful and elegant and over
$20,000 — much too expensive for
the 1981 market.

Steve Jobs of Apple got access to
look around inside PARC and a year
later Apple's Lisa came out. Priced

around $10,000, it did not sell very
well either. But it attracted lots of
attention. Then Apple tried again
with the Macintosh, which was
originaUy priced at $2,495. The PARC
vision was finally within reach of the
general public.

In the above three computers, both
software and hardware systems were
custom designed as one complex
unit. But underneath the spectacular
screens were ordinary computers.
The hardware had the same input and
output requirements, the same
memory management problems. The
PARC graphics environment was
simply an overlay — which in theory
could work with any operating
system on any computer.

The challenge of creating a single
graphics environment overlay which
would be compatible with many dif-
ferent computers was taken up by
Digital Research, Inc. of Monterey,

INSIDE GEM

GEM works by setting up an imagi-
nary all-purpose input-output
graphics device, called a Virtual
Device Interface (VDI). All graphics
I/O is sent through it. This will sound
familiar to programmers who have
used the Atari CIO. The GEM VDI and
IBM both follow the emerging
American National Standards Institute
(ANSI) standard of a memory location
grid 32K wide and 32K high.

Real-world devices, such as
monitor screens, touch tablets,
graphics printers, plotters, and mice
are usually much smaller. The ANSI
stiindard requires the necessary scal-
ing be done by the application pro-
gram or the device handler (they call
them device drivers), guaranteeing
compatability over a wide variety of
actual devices. GEM calls this the Nor-
malized Device Coordinates mode.

GEM supports another VDI mode
called Raster Coordinates (RC). This
allows you to map the actual device
coordinates over a portion of the VDI.
It was designed with monitor screens
in mind and permits addressing pix-
els directly, just like bit-mapped
graphics. RC allows multiple screens
to be created within the 32K by 32K
VDI grid. You can then switch be-
tween them.

The GEM VDI supports over 50
functions. These are like the XIO
functions and the AUXl and AUX2
bytes in the Atari CIO. They handle
setup of devices with defaults, graphic
primitives like lines, polygons,
ellipses, arcs, and others. They con-
trol color registers, Une style, character
fonts and cursor forms. They also sup-

California. DRI had developed the
first microcomputer operating
system, CP/M. Now they produced
the Graphics Environment Manager,
GEM.

Although it may well run on other
operating systems in the future, GEM
is currently available for IBM PC-DOS,
and for the closely related MS-DOS
and Concurrent DOS.

GEM MEETS ATARI

GEM has now also been chosen for
the upcoming Atari ST computers. It
will work with the new TOS
operating system, which is a close
relative of DRI's CP/M.

In the Atari STs, the GEM overlay,
the TOS operating system, and the
device drivers including hard disk,
floppy disk, Centronics parallel, and
RS232C serial are all to be contained
in 192K of ROM . That means when
you turn on your ST it is ready to
work immediately and none of your
RAM has disappeared.

GEM does more than make com-
puters easy to understand and use,
with flashy icons and drop-down
menus. It also supports multi-tasking.
That means that you can run several
programs at the same time and easily
pass information between them. It is
what we all thought computers could
do before we got one.

GEM's powerful graphic capabili-
ties are available to application soft-
ware, so terrific drawing programs
and spectacular games should be the
order of the day. In the multiple win-
dows you could run your word pro-
cessor and your spreadsheet at the
same time. Programs that we never

dreamed possible will be!

device capabilities.

BUILT-IN LIBRARY

GEM includes a package of subroutine
libraries in the Application Environ-
ment Services (AES). These libraries
handle the program's interface with
GEM, taking care of icon manipula-
tion, drop-down menus, windowing,
information transfer between applica-
tions, and a host of other details. This
makes the GEM magic much easier to
program. Digital Research also has just
finished a GEM Programmer's Toolkit
manual to aid in commercial program
development.

Because GEM runs on many
machines, most notably the IBM, pro-
grams are easily moved between
operating systems. Consequently, it is
believed that high quality IBM pro-
grams running under GEM will soon
be available on the Atari. But this can
work the other way, too. Atari pro-
grammers will be able to sell their
creations in the IBM market. Finally,
Atari owners will get some practical
large-scale business programs and IBM
owners will get some decent games.

The user interface in computers has
come a long way in a very short time.
We Atari users have had one of the
best all along. GEM will be another
giant leap forward.

Charles Cherry is a theatre techni-
cian who uses his Atari to generate
images for industrial slide shoivs, as
a moving message center, as a tele-
prompter and as a business machine.

In case you weren't aware of this,
it's a matter of honor at Antic to
use only Atari computers in our
office. And since we are a publi-
cation, word processing software is
used around here a lot.

We've noticed there are two
schools of thought about word pro-
cessing software for the Atari. Atari
users who haven't had experience
with other makes of computer are
reasonably satisfied. But other Atari
users who've had some exposure to
machines with more of a "business
computer" image unfortunately
know better. . .

Antic had been using LJK's Letter
Perfect as our in-house word proc-
essor— although without any great
enthusiasm for it.

We'd found Letter Perfect to be
rather more powerful and fuller-
featured than AtariWriter or Text
Wizard, the only other established
"serious" Atari WP software.

Probably just as important to us was
that only Letter Perfect would work
with the 80-column cards we had at
a couple of workstations. This advan-
tage tended to make up for the pro-
gram's files requiring a tedious con-
version process anytime we needed
to transfer in or out of standard Atari
DOS.

Included in Ibronto, the Antic
Editorial Department cheerfully
retired our Letter Perfect.

Every once in a while, a piece of
software or hardware shows up here
that is so clearly superior in its
category to anything else available for
the Atari that Antic starts using it in-
house immediately. The previous ex-
ample of this was "DISKIO" (January,
1985) that at once began replacing
DUP.SYS on our program disks.

Simply, Paperclip is by far the best
word processor ever available for the
Atari. It boasts a line-up of advanced
features that would be hard to match
on even the biggest-name word pro-
cessing software costing $300 or
more.

Paperclip makes your Atari the
word processing equal of just about
any computer on the market. Yet it is
not hard to learn and sells for only
»59.95.

Some nuts and bolts information:
Paperclip runs on aU Atari computers
with 48K. It comes on a disk that you
can back up. But the program is pro-
tected by a special key that plugs into
joystick port 2.

UNIQUE FEATURES

To justify our enthusiasm for
Paperclip, here are some of its most
distinctive features:

• DUAL WINDOWS— You can
display two text files onscreen at
the same time. And you can easi-
ly move blocks of text between
file windows.

• ONE-KEY MACROS— You can
easily set up for one keytouch
while pressing [START] to type
in an entire word, phrase or
paragraph that you regularly use
in your writing.

Basert^ Included said the final ver-
sion would hold files of about 20

XL models will contain about 28K

To set the print format commands
for boldface, underline and italics,
you must specify whether it is the
inning or the end of the format-
ection. We found this cumber-
some, especially when so many of the
other commands are so convenient.

There are still a few things that Let-
ter Perfect does which we wish
Paperclip would also do. For exam-
ple Paperclip does not have a com-
mand deleting an entire word, foward
or backward.

Although this word processor

comes withlan unpreceSeiMKd num-
ber of optiotubjOpr some reason it does
not let you turn off the keyclick in the

onscreen help files, pitch control,
page length setting, nearly 30 dif-
ferent printer drivers plus a configura-
tion menu, and on and on. . .

Yet for all the power it offers.
Paperclip is surprisingly easy to learn.
This is unusual, because the more
powerful editors are usually harder to
master. But PaperClip is virtually as
easy to use as Bank Street Writer
so there is no reason why it shouldn't
be your first word processor.

Many of the editing functions are
accomplished by holding down the
[CONTROL] and [SHIFT] keys
together plus a third key. With very
little practice, this becomes second
nature. And it also makes for an effi-
cient command structure.

For instance, [DELETE] removes
the character to the left of the cursor,
[CONTROL] [DELETE] removes the
character beneath the cursor [SHIFT]
[DELETE] removes the entire cursor
line. [CONTROL] [SHIFT] [DELETE]
gives you a choice of deleting to the
[E]nd or [T]op of the file.

AND STILL MORE...

This review is based on the ex-
periences of the four Antic editors
during this first first month when we
prepared an issue of the magazine en-
tirely with Paperclip.

We wanted to tell you about this
product as soon as possible. But the
fact is that PaperClip even has a lot
of other powerful features we simply
haven't had a chance to work with
yet. Plus there's one or two we've
been told about that are still in
development.

So at this time all we can do is list
the most important extra features (We
don't even have room for all of them)
and promise to cover these extras in
a later article or articles. . .

• TWO COLUMN PRINTOUT

• BUILT-IN MATH CALCULATOR

• MAILMERGEWITHSYNFILE-t-
— Both programs are by the same
authors, Steve Ahlstrom and Dan
Moore, althougliSYNFILE-f was
written in FORTH.

• MULTIPLE DISK FILE GLOBAL
SEARCH — Up to 6 simultaneous
search and replace operations
throughout all linked disk files
in as many as 4 separate drives.
Truly amazing.

• ATVRIWRITER-PAPERCLIP FILE
CONVERSION— Antic Con-
tributing Editor Jerry White is
writing this one.

• MIXED TEXT/GRAPHICS
SCREEN DUMP— This integrated
screen dump will enable you to
mix text and high-resolution
Atari graphics (modes 7. 5 and 8)
on a single printed page. It's
compatible with Micro Il-
lustrator and most other graphics
software files.

OUR RECOiylMENDATION

To sum up, if you do any exten-
sive amount of Atari word proces-
sing— whether it be as a student,
business person or professional —
you should get PaperClip right away.
If it's not in your local stores yet, buy
it by mail from Batteries Included.
(You don't weerf PaperClip if you only
write occasional short letters at
home. For that minimal level of use
you should probably look first at
Batteries Included's 849.95 Home-
Pak which was reviewed in the
March, 1985 Antic.)

SPEAKER — The console SPEAKER is
controlled by register SDOIF (53279)
decimal. This is the same location as
for the console keys. To start the
SPEAKER clicking, POKE in a number
between 0 and 7. The continuous
loop

I POKE 53279,0: GOTO 1
will generate a continuous humming
noise. In the XL series, the SPEAKER
noise is routed to the television
SPEAKER.

Infrequently Used BASIC
Commands

STR$ — In BASIC, the STR» com-
mand converts a number or numeric
variable to a STRing. You will also
need a string variable name to place
the string into if you want to use it
somewhere else. ONE23$ = STR$(123)
will assign the string "123" to the
string variable ONE23$.
VAL — In BASIC, VAL performs the
opposite function as STRS. VAL con-
verts a string which is made of nu-
meric characters to a numerical
variable or value. X=VAL(Y$) will
assign the value of 123 to the variable
X if Y$ were a string called "123". If
Y$ is an alphabetic character, an error
will result. f^

The new Atari ST computers will contain the Motorola
MC68000 microprocessor chip. Introduced in 1979, it was
the first l6-bit microprocessor to have 32-bit internal archi-
tecture with 16-byte, non-segmented direct memory ad-
dressing, which means you can potentially access
16,777,216 bytes. That's over 5,500 pages of single-spaced
typing. For programmers used to Atari's old 6502 chip,
it's a whole new ball game.

BASIC BABEL

Most Atari programmers started with the BASIC that came
with their machines. Many grew tired of its limitations,
and evolved to the powerful, highly precise world of
machine language.

Some argue this pattern will change with the new STs.

Jeffrey Gortatowsky, writing on the CompuServe Atari
SIG, says the pattern of this evolution was caused by the
design and memory limitations of the 6502. If you want
to write effective speedy software for a computer that has
only 64k memory available, you must use assembly lan-
guage. The code produced by high-level language takes
up too much memory and, on the 6502, is usually not
fast enough.

HIGH-LEVEL FUTURE

Gortatowsky then argues that, in the 68000, we will see
the beginnings of change. The chip architecture is so flex-
ible and fast, and the addressable memory so vast, that
high-level language will become the practical choice of
software manufacturers because time-consuming, costly
assembly language will no longer be necessary. In addi-
tion, private owners may find that any form of BASIC
which takes advantage of this chip's power is going to be
cumbersome and difficult.

This theory is echoed in the fme reference book, 68000
Assembly Language Programming, by Kane, Hawkins

& Leventhal (Osborne/McGraw-Hill, Berkeley, CA, 1981).
'We expect the future wiU tiavor high-level languages."

As chips and hardware become cheaper and more
powerful, the theory goes, the cost of programming labor
is rising. This helps explain the shift to efficient high-level
languages for program development. These languages can
also permit standardization of software development be-
tween machines.

A case can also be made that successful research in high-
level structured languages is lagging behind hardware
breakthroughs — which means that dramatic improve-
ments in features such as ease of use are somewhat over-
due and might be expected to happen reasonably soon.

Until then, it is not surprising that professional program
developers are specifically being told by Atari to use C or
Pascal on the STs.

There are two forms of C currently available for the
Atari. Deep Blue C, which can be ordered from the Antic
catalog, and C/65which you can get from Optimized
Systems Software. Because of the Atari computers' cur-
rent memory limitations, neither of these C versions are
full implementations of the language. They should,
however, serve as good training for those who wish to
learn C.

The new ACTION! language, also from O.S.S. is a cross
between C and Pascal. It's fun to program with and would
also be an excellent training ground for those interested
in learning structured programming.

In the computer world outside Atari, C is rapidly
becoming more and more popular among home program-
mers. Does this mean BASIC is on the ropes? Not really.

A choice of BASIC or Logo — in versions designed by
Digital Research who created the GEM operating environ-
ment used by the ST— will be bundled with the first ST
machines. And there is such an established, wide base of
BASIC programmers, it's doubtful the language will
disappear

New BASICS are likely to appear which will take advan-
tage of extra memory and aU sorts of easily-used new com-
mands will be added. The original structure of the
language, however, probably will remain the same.

MEMORY LIMITATIONS

And what about assembly language? We think memory-
efficient AL will be as necessary and popular on the STs
as on the earlier Ataris. Unlimited memory is not really
available. The 68000 microprocessor may be capable of
addressing 16 mega-bytes of memory, but, of the two an-
nounced ST models, the 130ST (S399) will contain only
128K of RAM and the top-line 520ST ($599) will have
512K.

On the IBM PC the highly touted Symphony, written
in a high-level language, requires 340K just for starters.
Framework, also written in a high-level language, will
operate (barely) in 256K on the IBM PC— but its tutorial
disk will not!

Atari says the new STs have non- expandable memory.
We suspect it won't be long before some imaginative third-
party manufacturer figures out a way to plug more
memory into the "non-expandable" STs. But meanwhile
if a software developer wants to market a program that
will run on both ST models, assembly language may be
the only viable solution.

HACKER'S PLEASURE

A consideration not taken into account in all this is the
pure satisfaction that assembly language programmers get
from programming at the nitty gritty level. We're no longer
talking about the practical, economic business approach,
but the home hacker who wants to roll up his sleeves and
get to know every board, chip and register in that machine.
He does not want to be limited by someone else's idea
of what the processor can do. If he wants a high-level
language, he writes a high-level language.

For those 6502 hackers, we offer the following preview
to whet your ST appetite. And this is simply an hors
d'oeuvre. Further details and definitions must be saved
for later articles. If you can't wait, we recommend you

Language Programming, or The 68000: Principles
and Programming, by Leo J. Scanlon, Howard W. Sams

68000 OVERVIEW

There are two operating modes in the 68000: User and
Supervisor. Certain instructions in supervisor mode are
not available in user mode. The supervisor mode is a pro-
tection against operator misuse, in sophisticated, multi-
tasking systems. It should be interesting to see what Atari
does with the supervisor mode.

Other niceties include built-in debugging aids, traps
against illegal addressing and illegal instructions, a one-
step trace mode, and seven levels of vectored interrupts.
Most of these are only available from the supervisory
mode.

DATA TYPES

Although the 68000 has a l6-bit data bus, meaning that
2 bytes of information can be accessed in one machine
cycle, internally it can operate on five different types of
data: bits, 4-bit binary coded decimal (BCD), 8-bit bytes
(B), l6-bit words (W), and 32-bit long words (L). Because
of this, byte data may be addressed at even or odd ad-
dresses, but words and long words must be addressed at
even addresses. For example, three bytes in a row could
fall at addresses S0004, $0005 and $0006, three words
at S0004, S0006, $0008, and three long words at $0004,
S0008, $000C.

The 68000 has 56 instructions and 14 addressing
modes. This is very similar to the 6502. But there are 17
general-purpose 32-bit registers. Eight are considered data
registers, seven are address registers, one is the stack
pointer and the last is the program counter.

THE REGISTERS

All of the data registers are general purpose and can be
used as index registers or counters. They can handle bytes,
words, and long words. The address registers are primarily
designed to hold addresses, but can be used as index
registers. Unlike the data registers, they cannot handle 8-bit
bytes.

The stack pointer can also be used as a general purpose
address register. It is actually two registers and will con-
tain different data depending upon whether you are in
supervisor or user operating mode.

The last 32-bit register is the program counter and,
although it is a 32-bit register, only 23 of the bits are used.
Since instructions consist of words instead of bytes, the
counter can access a range of 8M words, or 16,777,216
bytes. 6502 programmers will feel like a gnat in the
Houston Astrodome.

STATUS REGISTER

The last register in the 68000 is the l6-bit status register,
which is divided into two 8-bit bytes. The lower 8 bits
are for the user mode and the upper 8 for the supervisor
Not all available bits are used. The user flag bits are:

BIT

2
3

5-7

SYMBOL

(Unused)

CONDITION

Zero

Negative

Extend

BIT

SYMBOL

CONDITION

Carry

Overflow

Supervisor status flag bits 8 through 9 are used in various
combinations to signal interrupt priority for the seven
levels of interrupt. The 13th bit switches the modes be-
tween supervisor and user, and the 15th bit places the
68000 in trace mode. Bits 11,12 and 14 are unused.

ADDRESSING MODES

As stated above, there are fourteen addressing modes:

1. Data register direct

2. Address register direct

3. Register indirect

4. Register indirect with post-increment

5. Register indirect with pre-decrement

6. Register indirect with displacement

7. Register indirect with index

8. Absolute short

9. Absolute long

10. PC relative with displacement

11. PC relative with index

12. Immediate

13- Quick Immediate
14. Implied register

Given the number of registers and data types, the flex-
ibility of register use, and the amount of indirection in-
dicated in the address modes, there is incredible power
available in the 68000.

MC68000 INSTRUCTIONS

Table 7 is a chart of the 68000 instruction set mnemonics
with brief definitions.

Some instructions will be familiar to 6502 programmers,
but many will be completely alien. There are no LDAs or
STAs for example, because the 68000 is not accumulator
bound. There is the remarkable MOVE which will move
anything from anywhere to anywhere else.

Programming syntax for the 68000 on currently avail-
able assemblers is identical to popular 6502 assemblers,
in that each line consists of:

Line number (Label) Mnemonic (Operand) (Comment)

The mnemonic field, however, may contain a three, four
or five letter mnemonic, and instructions can occupy from
one to five words in memory.

More power and
speed from BASIC

I.earn how to nianil}tilate the
Variahh' Ncinie 'liihle and Van'dljle
Value Table in }X)ur BASIC programs.
Professional pn)grammers use these
powerftil techniques to add speed
and i:ariety to their code. The BASIC
listings work with all Atari com-
puters of any memory size.

If you program in BASIC, you've
almost certainly used string vari-
ables to store and manipulate
character strings. In this article,
we'll see how Atari BASIC handles
string variables. Then we'll show you
how to use this information to
harness the impressive power and
speed of string manipulation in Atari
BASIC.

These techniques come in handy

whenever you have to move or
modify a large area of memory. Some
possible applications are: redefining
character sets, changing display lists,
manipulating machine language pro-
grams from BASIC, moving players in
Player/Missile graphics, and changing
screen memory for animation or page
flipping.

VAmABLE TABLES

Atari BASIC uses two tables to keep
track of the variables in your program:
the Variable Name Table and the
Variable Value Table.

The Variable Name Table holds the
names of all the variables used in your
program. It also tells the computer if
a variable contains a string, a number,
or a numeric array.

The Variable Value Table records

the size and
contents of each
variable.

Whenever you use
a new variable, wheth-
er it's in a program or
a direct command, the
computer updates both
tables. Moreover, when you
SAVE a program to disk or
cassette, the tables are saved
as well. Both tables will remain
in memory until you LOAD an-
other program, issue a NEW com
mand, or turn off the computer.

FINDING TABLES

The location of these tables in C
memory depends upon the length of |
your program. To find them, we g
check the contents of four special 3

ANTIC, The Atari Resource

memory locations which point to the

start of the tables. These are:

VNTP = PEEK (130) + PEEK (131) *

256

WTP = PEEK(134) + PEEK (135) *

256

VNTP is the starting address of the
Variable Name Table and VVTP is the
starting address of the Variable Value
Table,

The Variable Name Table stores the
names of all variables in the order
they appear in your program listing.
It also stores the type of each variable
(string, numeric, or numeric array).

Listing 1 displays the contents of
the Variable Name Table in a readable
format. The subroutine in lines 1000
through 2005 can be appended to any
BASIC program for a listing of the
variables used. Type in Listing 1,
check it with TYPO II and SAVE a
copy.

INTERPRETING TABLES

The Variable Value Table tells the com-
puter where to find the contents of
each variable. It also contains the size
of each variable. It uses eight bytes per
variable to store this information.
We'll refer to these bytes as byte one,
byte two, etc.

Byte one determines whether the
variable represents a string or a
number (A 129 in this location would
denote a string variable.)

Byte two is a reference number (0
through 127) assigned to that variable.
This is the number which the com-
puter uses to identify each variable.

Byte three and byte four tell the
computer where it can find the con-
tents of the variable.

Byte five and byte six contain the
length of the variable, and byte seven
and byte eight contain the maximum
size of the variable. In the case of
string variables, this value is equal to
its dimensioned length. For example,
consider the BASIC line:

10 DIM AJ!(12):AS = ' ABC"

In this case, AS is three characters
long, but its maximum size is 12.

Interpreting bytes three through
eight requires an understanding of
how the computer stores numbers in
memory locations. A single memory

location can only store numbers be-
tween 0 and 255. The computer
breaks up larger numbers into two
parts and uses two memory locations
to store them.

The first location contains the
number of 256's in the number Pro-
grammers refer to this as the "high
byte" of a number. The second loca-
tion, the "low byte," contains the rest
of the number

To calculate the size of a string
variable, we multiply byte five by 256
and add byte six. We used the same
method to calculate the starting ad-
dresses of the Variable Name Table
(VNTP) and the Variable Value Table
(WTP) at the beginning of this article.

Finding the location of a variable
in memory is slightly more compli-
cated. Strings and arrays are stored in
the String and Array Table. Byte three
and byte four contain a pointer, or
"offset value" used to locate a variable
in this table.

First, multiply byte three by 256,
and add byte four to determine this
offset value. Now, add this to the start-
ing address of the String and Array
Table. This address can be found with
the equation :STARP= PEEK (140) +
PEEK (141) * 256. The final value is
the actual address of the string. You
could also find this address with
BASIC'S ADR function.

The location of the String and Array
Table varies with the size of your
BASIC program. For this reason,
references to this table should only be
done under program control, not
through direct commands.

Listing 2 will display the values of
byte one through byte eight for each
string variable in the Variable Value
Table.

Listing 3 takes the same informa-
tion and interprets it for you, printing
the actual size and location of each
string variable in the program. Both
of these listings should be checked
with TYPO II and SAVEd before you
RUN them,

LOCATING VARIABLES

Searching through the variable tables
for information about a particular
variable is a complicated, error-prone,
and often unnecessary procedure. We

can easily design and build our own
variable tables, if we follow one
simple rule: The order of variables in
the tables must be the same as the
physical order of the variables in your
program. Consider the following
program:

10 DIM A$(3):A$ = "ABC"

20 GOSUB900

30 DIMBS(3):B$ = "DEF"

40 END

900 DIMC$(3):CS = "GHI"

910 RETURN

In this program, AS will be the first
variable in the variable tables because
it's the first variable in the program.
BS will be the second, and CS will be
the third. (Note that the computer
builds the variable tables according to
the physical order of variables in your
program, NOT the logical order)

If you want to manipulate a variable
through the variable tables, it's wise
to declare that variable in the first line
of your program. This places it at the
top of your variable tables.

Remember to type NEW before
typing in your program to assure that
no information is left in the tables
from earlier programs or direct
commands.

If you forgot to do this, you can
LIST the programs to disk or cassette,
type NEW, and ENTER the program
again. Do not use SAVE and LOAD
since these commands save the
variable tables along with the
program.

CHANGING VARIABLES

Both variable tables are in RAM which
means that their contents can be
changed using BASIC'S POKE
statement.

For example, suppose we wanted
to change the name of the first
variable used in Listing 1 from AS to
BS . Since AS is the first variable used,
it will be at the beginning of the table
and its name will be in location VNTP.
LOAD in Listing 1 and then type:

POKE VNTP, ASC ("B")

Now LIST the program. All refer-
ences to AS are now BS.

VALUE TABLE CHANGES

More powerful effects can be achieved
b)' changing the Value Table. By
changing a string variable's entry in
tliis table, we can position it anywhere
in memory. We can also change its
size.

If we place our string variable in a
region of memory used for other pur-
poses, we can use it to change those
memory' locations. For eximple, if we
relocate a string variable to an area
reserved for Player/Missile graphics,
we can control the players with
several well-placed POKEs to the
variable tables.

To do this, of course, you'd need a
working knowledge of Player/Mis-
sile graphics, and that's beyond the
scope of this article. Instead, we'll
relocate a string variable to screen
memory. In this way, we'll change
what's on the screen by changing the
appropriate entries in the Variable
Value Table.

Recall that the Variable Value Table
contains information about the loca-
tion of string variables. This informa-
tion is kept in bytes three and four in
the table. In Listing 3, AS is the first
variable dimensioned. Since its byte
one value is in memory location
■WTP, its byte three value can be
found by PEEKing (WTP + 2), and
its byte four value is in (WTP -i- 3).

SLIDING STRINGS

Let's move A I to screen memory. The
address of the beginning of screen
memory is calculated in line 100 of
listing 3, and stored in the variable
SCRN.

Next, we use SCRN to calculate AS's
new byte three and byte four values
for the Variable Value table. Use the
following formulas:

Offset = (new location)-
(PEEK(140)-PEEK (141) *256)

Byte four = INT (Offset/256)

Byte three
Bvte four

= Offset-
256

Lines 150-170 perform these
calculations. These new values are
POKEd into the Variable Value table

in line 200. These POKEs slide the
contents of the string variable into
screen memory.

Lines 250-290 change the vari-
able's size by altering the values for
bytes five and six in the Variable
Value Table. We can calculate the
new values with these formulas:

Byte sbc = INT (size/256)

Byte five = size-byte six * 256

In this example, we use a size of 400
bytes. This allows us to control the top
ten lines of the Graphics 0 display
screen.

MODIFYING MEMORY

Once relocated, a string variable can
be used to modify the area of memory
it occupies. Manipulating the string
contents alters the contents of the
memory locations. An example is the
line:

A$ = 'ABCD "

This will put a 65 in memory loca-
tion SCRN, 66 in SCRN + 1, 67 in
SCRN -H 2, and so on. Since we are
dealing directly with the screen, we
must use internal character codes
rather than ATASCIl. In line 400 of
Listing 3, AS is completely filled with
CHR$(0), the ATASCIl "heart"
character This puts a 0 in the first 400
locations of the screen memory area,
and 10 blank lines are on the screen.

Line 420 puts the word "HELLO"
on the second line of the screen by
placing the characters "(%,,/" into
AS, and then sliding AS to screen
memory. In this example, when a 40
(ATASCIl code for a left parenthesis)
is POKEd into screen memory, the let-
ter "H " appears on the screen.

The speed you can achieve with
this "string sliding" is rivaled only by
machine language. Imagine the
graphics effects possible!

FOUR STEPS

Four basic steps are needed for posi-
tioning string variables in memory:

1. Dimension the variable in the
beginning of your program.

2. Calculate WTP, the starting ad-
dress of the Variable Value Table, from
locations 134 and 135-

3. Select a new memory location for
your string variable, break the address
into low and high bytes, and POKE
these new values into the Variable
Value table at byte three and byte four.

4 . Calculate the new size of the string
variable and place these values into
byte five and byte six. Byte seven will
contain the new value you need for
byte five, and byte eight will contain
the value you need for byte six.

Once the string variable is posi-
tioned, characters in the string will
correspond to numbers in the
memory locations. This method can
be used to place numbers in memory
by placing characters in the string.
You can also to read numbers from
memory by reading the string.

A string can even be positioned in
the area of memory where a program
is stored — resulting in a program that
can write other programs! As you
learn more advanced programming
techniques, you'll discover many
more uses for relocating string
variables.

to immediately determine
what programs lie on each disk and
run them, without switching between
BASIC and a DOS menu.

What you need is a menu program.
What?", you say, "Another menu pro-

Ah — hut Lazy Loader is different. It
allows you to enter LISTed BASIC pro-
grams, reads up to four disk drives,
and displays up to 51 files with
horizontal scrolling.

USING THE PROGRAM

Type in Listing 1 and check it with
TYPO II. SAVE it to a disk under the
file name LAZYLOAD.BAS.

You can RUN the program right
nt)w and see all the BASIC files on
yoLir disk. Or, \'ou can have the menu
automatically boot with the disk by
including an AUTORUN.SYS file. (See
accompanying article for more infor-
mation about AUTORUN.SYS files.

The file names will appear in a col-
umn in center screen. If you have
more than 17 files, the column will
scroll to the left one line at a time as
a second column appears.

Because Lazy Loader is designed to
handle BASIC programs, it will not
display files with the extenders .SYS,
.OBJ, .EXE, or .DAT.

Each file name is displayed with a
letter, from capital A to Z, then lower
case a to z.

To run a program, strike the cor-
responding letter. When choosing a
file with a lower case letter, be sure
that you are in lower case mode. This
status will be displayed in the upper
left corner.

If you want to see the file names of
a different drive, choose the ap-
propriate dri\'e number (1-4).

ENTER OR RUN

In addition to RUNning tokenized or
SAVEd programs. Lazy Ix)ader EN-
TERS untokenized, LISTed files. Again,
just press the key corresponding to
the program you want. You don't
need to press [RETURN].

If an error should occur, its number
appears in the upper right corner.
Press [RETLIRN] and the program will
continue.

To read a new disk in the same
drive, swap disks and press [RE-
TURN]. To run DOS from drive 1,

press [CTRL D].

As pan of its regular procedures,
the DOS prognini looks for a binary
file named Al'IOlUN-SYS. If
.'VUrORl'N.SYS is present, it is
loaded into memory and RUN.
Otherwise, DOS coiuinues with
other operations such as running
the DUP.SYS file.

CREATING AUTORUN

The AUTORl'N.SYS file must be a
machine language program, but we
can use a BASK '. program which will
create an AIJTCMU N-S^ S file. In this
issue's Listing Section and on the
monthly Antic Disk. \ou '11 find such
a program, calletl .\RSMAKER.BAS,
(for ALCrORUN.SYS MAKER), We
found ARSMAKER.BAS in David
Mentley's invaluable ABCs of Atari
Computers (available from the
Antic ("atalog) and it is reprinted by
permission of the publisher,
Datamost.

'I)|)c in Listing 2. clieck it with
lYPO I( and SAM-: a copy

ARSMAKE.R.BAS creates an
AirrORUN.SYS file that automati-
cally runs any program of your
choice. When you RUN ARSMAKER
.BAS, the program will ask you to
"Enter filename to auto run." At the
? prompt, type the file name, in this
ca.sc the name you've given Ltzy
Loailer. followed by a [RETURN].
(Dont t)pe device code 1):). \bu'll
need to do this only the lirst time
you RUN ARSMAKER.BAS on a
given disk.

You now have a disk with DOS
2. OS, Lazy Loader, and a file named
AUTORUN.SYS. When you boot this
disk, the Atari automatically loads
the I")()S program, which automati-
cally loacU the .U'TORUN.SYS file,
which automaticaUy runs Lazy
I^)ader.

If u)u have an Antic Public
Domain Disk or a monthly Antic
Disk, here's a shortcut. Use DOS to
change the name Laz>' Loader or ;uiy
other fUe to MENTJ. You can use the
AUTORUN.SYS program that's in-
cluded on each disk, since it will run
any program named .Ml'.NU. — M.C.

Multiple graphics
modes on one screen

Mode Mixer rs a utility program for easily creating
custom display screens that use multiple graphics modes,
ami then saving thcnt to disk foi lat-'r use in ) our own
[jro^rufns Writ Icti in BASIC, M' r ret/ in res a disk

drive and will run on all Ala -lens with 32K,

depending on screen /ise.

DISPLAY LIST

The Atari's video display is created by a special
microprocessor chip called ANTIC. (Yes, as in the
title of your favorite magazine.) ANTIC can present
information in 14 different graphics modes, six for
text and eight for plotted graphics.

Only nine of these modes are available directly from
BASIC on the old Atari 400 and 800 computers, but 13
of them can be accessed in BASIC with the XL models.
The graphics modes differ in their horizontal and vertical
resolution, number of colors shown, and amount of
memory consumed {Table 1).

The program which tells ANTIC what kind of display
to show is called a "display list". A nice introduction to
display lists and mixed-mode principles is found in
"Display Lists Simplified" (Antic, Feb/Mar 1983). "Unlock-
ing the 56 Graphics Modes" (Antic, Sept. 1984) illustrates
all these modes and provides more information about the
Atari's video display.

A BASIC graphics call will only give you a screen of one
mode (with the exception of windows). To construct a
mixed-mode display, you must create a display list to tell
ANTIC how many "mode lines " of each desired graphics
mode to show. The resulting screen is made up of several
horizontal bands or segments, one band for each block
of lines in a particular graphics mode.

The display list also contains some other information,
and a few tricks have to be played to print or plot cor-
rectly in the different segments. For each graphics mode,
one mode line consists of a specific number of horizon-
tal TV "scan lines", ranging from 1 for ANTIC mode 15
(GRAPHICS 8) to 16 for ANTIC mode 7 (GRAPHICS 2).
A complete screen must contain 192 scan lines. Keep these
numbers in mind as you use Mode Mixer.

ANTIC, The Atari Resource

USING MODE MIXER

Type in Listing 1, check it with TYPO II, and SAVE a couple
of backup copies. RUNning the program shows you a
menu. Just press a number key to choose a menu selec-
tion; it is not necessary to press [RETURN]:

1. Create a New Display: Begin with this option. "Vbu
will see a screen which prompts you to enter the ANTIC
graphics mode (2-15) for the first segment. Then you can
specify the number of mode lines for that segment. Con-
tinue this process for all the segments in your display. The
table at the top of the screen keeps a running description
of your display as you compose it. Keep an eye on the
number of scan lines remaining, which goes down each
time you describe a new segment. The goal is for this
number to be zero when your display is complete.

You can enter up to 16 segments per display, combin-
ing the available graphics modes any way you like. When
prompted for a graphics mode, enter the ANTIC mode
number from Table 1, not the usual BASIC graphics mode
number To cancel an entry, enter zero for the number
of mode lines. When you have completed the descrip-
tion of your display, and wish to return to the menu, enter
zero for the next mode number.

Notice that selecting option 1 at the menu erases forever
any display already in memory.

2. Change the Current Display: Use this option to
modify the display currently in memory, whether you just
created it or loaded it from the disk. You will be prompted
for the segment number to modify, and then for the new
graphics mode and number of lines.

If the number of scan lines remaining is greater than
zero and the number of segments in the display is less
than 16, then you can add new segments to the bottom
of the display. When prompted for the segment number,
just enter the number one greater than the last segment
number already in the display. Also, you can erase a seg-
ment by setting the number of mode lines for that segment
to zero.

When you have finished editing the display, enter zero
for the segment number to change. You will return to the
menu.

3. See the Current Display: This function actually
generates the display list from your description of the
mixed-mode screen. The TV screen will be black briefly
while the calculations are done, and you will hear a tune
reminiscent of Woody Woodpecker when the computer
is done. At that point, you will see the mixed-mode display.
Admittedly, it isn't very interesting: just bands of blue (for
ANTIC modes 2, 3, and 15) and black (for all other modes).
In fact, you may not see anything at all. Rest assured that
all is well, however. After you hear the tune, press any
key to return to the menu.

4. Save Current Display on Disk: This part of Mode
Mixer writes a program for you and stores it on the disk.

First you will be asked to supply a file name. Use any legal
Atari disk file name, without extender Unless otherwise
specified. Mode Mixer assumes you mean disk drive one,
and it assigns an extension of ".DSP" to the file name you
give. If you try to save the display before you viewed it
with menu option 3, you will go through step 3 anyway.
The resultant file will be a BASIC program, stored in
LISTed form. We will talk later about how to use this
program.

5. Load a Display from Disk: Here you can retrieve
a display from the disk for further editing. MODE MIXER
shows you a list of all the files with extension ".DSP" and
you type the name of the file you wish to load. Enter a
zero if you decide not to load anything after all.

It takes several seconds for the program to read the file
and reconstruct the display description. When this pro-
cess is complete, you will be at the "Change the Current
Display" screen. Notice that using option 5 replaces any
existing display in memory with the one you load from
the disk.

6. Done With This Program: Choose option 6 to
leave Mode Mixer and return to BASIC.

STORED DISPLAYS

To use a stored display, type NEW to clear out any pro-
gram already in the computer's memory, then type ENTER
"D:filename.DSP". You can now RUN this program to
recreate the display as you described it to MODE MIXER.
This program consists of several parts:

1. Line 10, which calls a subroutine at line 30000.

2. Several statements which set up the various
segments in your display. Each begins with a POKE 87,n
command, where n is a BASIC graphics mode number.

3. An END statement at line 29999.

4. A block of statements beginning at line 30000 which
set up the display list needed by your mixed-mode screen.

5. A subroutine beginning at line 31000 which con-
trols memory allocation for each display segment.

The point of all this work so far is to help you get some
fancy displays on the screen. You accomplish this by think-
ing of each segment as a separate little screen. Following
each of the POKE 87, n statements you can insert any ap-
propriate text or graphics display commands. For text
modes (ANTIC 2-5) use POSITION and PRINT *6;
statements.

In the graphics segments (ANTIC 6-15), use PLOT and
DRAWTO commands. The upper left corner of each
screen segment is location 0,0. Be sure not to plot or print
outside the allowable horizontal and vertical boundaries

continued on next page

May 1985

of a segment, based on the number of mode lines you
have in each segment.

You can easily combine a program written by Mode
Mixer with any other BASIC program. Use the ENTER
command to retrieve the display program file from disk
and merge it with another program already in memory.
Remember that line numbers from an ENTERed file replace
any statements with the same line numbers in the existing
program when you do a merge operation.

AH EXAMPLE

Listing 2 is a sample program written by Mode Mixer. The
display specified has six segments: 4 lines of ANTIC mode
6; 4 lines of ANTIC 2; 20 lines of ANTIC I4; 4 lines of
ANTIC 5; 20 lines of ANTIC 15; and 6 lines of ANTIC 10.
Type in Listing 2 and LIST it to disk. Next, type in listing
3 and SAVE it. With listing 3 in memory, ENTER Listing
2 to merge the two programs, then RUN it to see a nice
demonstration of the kind of complex displays you can
produce using Mode Mixer and a bit of your own creativi-
ty NOTE: Press [SYSTEM RESET] after running any pro-
gram created using Mode Mixer.

OTHER TIPS

You can change the color registers as usual in a program
with a mixed-mode display. (Atari Color Graphics or
Atari Graphics and Arcade Game Design, available
from the Antic Catalog, fully describe what the different
color registers do in each BASIC graphics mode.) Using
display list interrupts (see "More Interrupting" in Antic,
Dec. 1983) to get different colors in different segments
will help create truly dazzling displays.

To get a uniform background color for displays in which
ANTIC modes 2, 3, or 15 are mixed with the other modes,
use a SETCOLOR 2,H,L statement, where H and L are the
hue and luminance of the desired background color (0,0
is the default). Unfortunately, this also makes any graphics
which use a COLOR 3 statement invisible.

I haven't forgotten about the three GTIA graphics
modes, BASIC modes 9, 10, and 11. These all use the same
display list as ANTIC 15, so just create a segment with
mode 15 with Mode Mixer. Then change the POKE 87,8
statement for that segment to a POKE 87,9 (or 10 or II,
depending on the (iTIA mode you want). You will need
to use display list interrupts to alter the GTIA location at
SDOIB for only the appropriate segments.

The XL computers ha\'e a BASIC mode number for all
ANTIC modes except 3- Programs written with Mode
Mixer will work fine on the XL computers. However, you
ma)' wish to change the "n" in the POKE 87, n statements
for segments of ANTIC 4, 5, 12, and 14 to the appropriate
BASIC mode from Table 1.

Line 15 of Listing 3 (POKE 752,1) prevents stray cur-
sors from appearing when printing in text segments of
a mixed mode display.

"The Atari is just a game machine."
Do those words set your blood aboil?
Well, the staff at Antic is tired of
them too, and spends a good portion
of its time diligently combing the in-
coming submissions for practical
applications programs. We receive a
lot of disk directory programs, recipe
file storers, mini word-processors,
and other rehashed versions of old
ideas. But now ive'd like to award Lh:
John C. Ferguson the Honorary
Antic Unprecedented Application
Program of the Year Award for his
fine Beer Party Atari. A program
whose time has come. —ANTIC ED

My wife and I decided to
have a party one even-
ing for a fairly large
\ number of workplace
acquaintances. The trouble with such
social gatherings is that "shop talk"
tends to predominate and guests don't
really get to relax and have fun. Our
answer to this concern was to orga-
nize the party around the distraction
of a "beer sampling" — to determine
which brand of beer is best. The Atari
provided an ideal tool to focus the
group's attention towards finding an

May 1985

This useful applications program
will keep track of the best brew in a
beer tastingparty. The programming
makes good use of custom display
lists and character sets. So non beer-
drinkers might wish to type it in and
change the name to Rootbeer Party
Atari. It is written in BASIC and will
run on all Atari comptders with 16K.
A disk drive is recommended, but the
article explains how to run the pro-
gram without one.

unbiased corporate answer to this im-
portant question.

We set up a table with five pitchers
containing different beers. These were
kept filled, out of sight, from cans of
popular brands kept on ice. Wliile the
guests knew which brands of beer
were involved, the pitchers were on-
ly labeled as "A", 'B", "C", "D", or "E".
The guests thus had to taste from each
pitcher and give the mystery beer a
rating. They could jot notes on a piece
of paper to help themselves
remember

After sampling and rating each of
the five beers, they then typed their
evaluations into the Atari. The pro-
gram I developed for this purpose
made it easy for even the most
computer-phobic in the crowd.

SOBERING INFLUENCE

The program provided a prompt for
entering the rating of each beer, and
then a chance to verify that all five
were keyed in correctly. It then
calculated the average accumulated
score for each beer, saved the data to
disk, and quickly showed a graphic
display of how the different beer
brands stacked up in the opinion of
the judges.

A lot of guests were very surprised
to see how swiftly the scores changed
as more and more people entered
their choices. It became almost like
a horse race! If things got close, the
numerical values of the average scores
could be displayed by pressing [S]
while the graph was onscreen.

VALUABLE DATA

Saving the data to disk after each set
of entries was a feature added to the
program to make sure that an accident
didn't happen to spoil the accumu-
lated results. It was fortunate that this
precaution was included, because a
power glitch did occur in the middle
of my party and wipe out the pro-
gram. However, I was able to quickly
reload it, recall the accumulated data,
continued on next page

and continue on as if nothing had
happened.

All in all, my beer party was a
tremendous success. Everybody had
a good time, and work worries were
kept well out of mind.

THE PROGRAM

Type in the program, check it with
TYPO II and SAVE a copy. Much of
the program is internally documented
with REM statements. When you RUN
it, the computer will first ask you if
you want to add to a previous file —
that is, do you want to start with data
saved from a previous run of the pro-
gram. The first time your answer
should be [N]. Note that if this choice
is taken, any previous file of BEER-
DATA will be deleted and replaced
with a brand new one. If you answer
[Y] you are given a chance to insert
the particular BEERDATA file disk you
want to add onto before the program
continues.

WITHOUT DRIVES

If you do not have a disk drive, you
can still use the program without this

feature. You should type REM after
line numbers 110 -160 and 1450. This
will update your scores in memory
without SAVEing them. It also
preserves the code for possible future
use when you do have access to a
drive.

MODIFIED CHARACTERS
AND DISPLAY LIST

Several programing "tricks" were
used to produce the varied and in-
teresting screen displays. Eirst, some
characters of the normal Atari font
were modified to produce graphic
representations of a beer stein and
pilsner glasses. (See lines 10000-
10200.)

Next, a customized Graphics 0
screen was produced by modifying
the display list to show several lines
of Graphics 1 and Graphics 2 (j^ro-
gram lines 1030-1055). Now, when
the altered characters, the normal text,
and the special Atari control charac-
ters are all put together, in any of the
the three sizes provided by the modi-
fied screen, the result is a really

sophisticated display. This was pro-
duced with remarkably little code —
Ah, the beauty of Atari!

NAME YOUR BRAND

When you use the program, you will
want to select your own five brands
of beer to compare. These should be
reprogramed into hnes 1550-1630.
Note which beer corresponds to each
code letter— you don't want to have
these mismatched. For my first party
I invested in a case of pilsner glasses
and a sufficient quantity of five
middle-line popular beers. Next year
I think I will do it again with an in-
ternational flavor— rating beers from
five different countries.

by ANDY BARTON

This enhancement (fffhe reniarkably
simple and /Mpular file program
from the December. 1 91^ i Antic pro-
vides an easy way to save, retrieve,
edit and delete short notes and data.
Writteti in BASIC] (heall-neiv version
is complete in this issue and ivill run
on any Atari conrputer ivith a disk
drive.

In the December, 1984 Antic we ran
a program called "Info Bits" by
Andy Barton, author of TYPO II.
Published primarily to demonstrate
how much can be accomplished with
a small amount of programming, we
described Info Bits as the "Simplest
database ever.'". We received many
letters from readers who loved the
program but wanted it just a little
less simple.

Specifically, they wanted to know
how to edit or erase some of the many
entries they were putting into their
"Info Bits" data files We contacted
Andy and received the following up-
date -ANTIC ED

INFOBrrS MODIFIED

.1 nfo Bits was originally written as
J a hasty last effort, after two
M rejections, to get something pub-
IP lished. It was purposely kept
short, simple and direct, with no frills
added. In this spirit, a "Delete Entry"
routine was not included. (And, to be
honest, I didn't think about it until
some time later when I found I had
no way to correct a typographical
error in one of my entries.)

TYPING THE PROGRAMS

Listing 1 is the new Info Bits. (File-
name: INFONEW.BAS.) Those of you
who typed in the original program
may notice a few matching lines, but
there are many changes so you will
probably be best served by typing in
all of the new listing. Remember to
check your typing with TYPO II and
SAVE a copy of the program before
running it.

continued on next page

May 1985

Listing 2 is a brief program which
corrects a bug in the original Info Bits
program by modifying its INFOBITS.
FIL data file. If you have no Info Bit
files yet, you can ignore this listing.
Those who wish to use their previous
INFOBITS. FIL entries with the new
Info Bits must use this program to
reconfigure their old files.

After typing in Listing 2 with a
TYPO II checkup and SAVEing a copy,
place the disk with a copy of your
INFOBITS.FIL on it. RUN listing 2 and
it will remove the leading 10 blank
spaces in front of each entry on the
file. Note: Listing 2 was kept pur-
posely short and contains no error
trapping. Make sure your disk con-
tains the INFOBITS.FIL before you
run the program.

USING THE PROGRAM

Info Bits is a mini data base. You can
type in notes and references and then
retrieve them by searching for a key
word or phrase — which can be
anything in your entries.

Before you can use Info Bits, you
must create an empty file named
INFOBITS.FIL on whichever disk is in
drive one. To create the file, type in
the following:

OPEN *I,8,0,"D:INFOBITS.FIL':
CLOSE *1 [RETURN]

After you've done this, RUN the
new INFOBITS and you'll see a menu
with three choices: l.)ADDTOFILE,
2.) SEARCH FOR ENTRY, and 3.)
DELETE/(EDIT) ENTRY.

ADD TO FILE

Press [1] [RETURN] and type in a
couple of entries, pressing [RETURN]
to mark the end of each entry. You
don't need any special characters to
mark off fields, simply type in a space
or two. Each entry can be as long as
119 characters.

When finished making entries,
press [RETURN] at the "TYPE
ENTRY:" prompt and you will return
to the menu.

SEARCHING FILES

To search for datii, type [2] [RETURN]
from the menu and you will see

SEARCH FOR:. You may type in a
word or portion of a word or a com-
plete sentence. Enter your search
criteria in capital letters and Info Bits
will ignore case distinction in the data
it searches.

After entering your search criteria,
press [RETURN] and Info Bits will
display on screen every entry that
contains an exact match of your
criteria. If there is more than one
screen, the program will pause and
prompt you to press any key for more.
If you wish to see all your entries,
enter ALL at the prompt.

DELETING AND EDITING

Type [3] [RETURN] to select DELETE/
(EDIT) ENTRY. The screen is cleared
and you are given 3 choices. First type
[S] [RETURN] to search for the entry
to be deleted. Repeat this step as often
as necessary until the entry you wish
to delete is the last one displayed.

Type [D] [RETURN] to delete the
last entry displayed. The actual entry
being deleted will be displayed on the
screen. If you are satisfied with the
deletion simply press [RETURN] to
return to the main menu. If not, press
[Y] [RETURN] to edit it. And when
you are ready to re-enter it again, press
[RETURN].

You are now in the ADD TO FILE
routine of the main menu where you
may continue adding entries when
asked to TYPE ENTRY:. Or simply
press [RETURN] on the blank line (an
absolutely necessary step to properly
close the disk file) and return to the
main menu.

The only safe place to exit Info Bits
(turn off the computer or load
another program) is from the main
menu. If you exit in the ADD TO FILE
or DELETE/EDIT routines the disk file
will not be properly closed and part
or all of it could be lost.

UPPER AND LOWER

Included in this version of Info Bits
is a short addition to the machine
language routine that allows it to
ignore the differences between lower
and upper case letters. This allows you
to type entries in caps and lower case

letters for aesthetic or other reasons
and later find them without having to
remember which way you entered
them. However, your search strings
must be in capital letters.

If you prefer the original version
which differentiates upper and lower
case letters, simply replace the 5th
through 10th numbers in DATA line
2002 with 234,234,234,234,234,
234.

Given the infallibility of computers
(ha,ha), not to mention that of the
operator or programmer, 1 highly
recommend that you regularly make
a backup copy of your disk file
(INFOBITS.FIL).

Many Antic readers owe Andy
Barton a vote of thanks for his TYPO
II line-by-line proofreading pro-
gram, ivhich we've been using with
all our BASIC listings since January.

Arena Racer is 15 scrolling levels of
fiercely challenging maze action.
Can YOU fly a speeding Huntercraft
through labyrinthian caverns and
avoid getting blasted apart by all
those Laser Cannons? This unusually
fast BASIC program works on all
Atari computers of any memory size.

Uh-oh! There's an intei^alactic war on
and you got shot down onto a rather
nasty planet. The local enemy war-
lord gets plenty of entertainment from
Elite Fighter Pilots like you — when
they're unlucky enough to fall into his
hands. (Yes, you are a rocket ace. You
only lost that last dogfight because
you were so vastly outnumbered.)

You arc tossed into an unarmed
Huntercraft and sent down to a hor-

B\l^RTiF SUTHERLAND

ror known as. . .the Arena! This
Arena is a vast maze of caverns. On
each of the caverns' 15 levels, you
must collect four glowing orbs, which
have been hidden and protected.
But ... as you fly among the twisting
walls of the Arena, scores of deadly
laser cannons are firing at you.

If you complete the fifteenth level
you get to start over again, with even
faster action. Your only reward is sur-
vival!! For you see, you are operating
under a strict time limit. If you do not
complete a level in time, your Hunter-
craft will disintegrate. HAHAHAHA!!
(We told you it was a rather nasty
planet.)

INSTRUCTIONS

Type in Listing 1, check it with TYPO

II and SAVE a copy before youRUN it.

When playing, you start with four
Huntercraft and win a bonus ship
after every five levels you complete.
Maneuver in any direction with the
joystick, even diagonally. Pick up an
orb simply by moving over it.

Your joystick trigger is the Panic
Button. As long as you hold it down,
your Huntercraft stays motionless and
is invulnerable to laser hits. The good
thing about the Panic Button is that
it never runs out of operating energy,
you can always use it.

ARENA RACER

continued from page 49

The bad thing about the Panic But-
ton is that it makes your time limit run
out faster. . . Is Arena a hard game to
play? All I can say is that I wrote it and
I've never gotten higher than 12 of the
15 levels.

PROGRAM TAKE-APART

Initial setup is done in Lines 1000 to
1070. This includes POKEing in the
machine language subroutine and
character definition.

The major action is found in lines
10 to 70:

10 Produces timer sound and
checks for OUT OF TIME

15 Draws current screen and
checks for PANIC BUTTON

20 Shuts off timer sound and
checks JOYSTICK

30 BOOLEAN LOGIC deter-
mines joystick dirction

40 Checks to see if you hit
somethins

50-60 If path is clear, lets you
move in that direction

70 Go back for more

Lines 80 to 280 check what char-
acter your ship has hit. The appropri-
ate action is then taken — pick up orb,
be destroyed by laser, etc.

CUSTOM SCREEN SETUP

The more adventurous of you can
create your own screens. It's not
exactly easy, but it can be done after
some trial and error.

The Arena is made up of an array
of 70 X 70 characters. DATA for the
levels is contained in lines 6000 to
6290.

Every second line, beginning at
6000, contains 70 characters arranged
in a pattern which makes up the walls,
spaces and cannons. Every second
line beginning at 6010 contains DATA
for placing the four orbs. You may
manipulate this DATA as you wish.
The only restriction is that first five
and the last five characters in each of

the screen DATA statements must each
be an 'A."

The screen DATA characters
represent:

A Solid line of wall characters

B Solid line of open spaces

C,D,F 3 different patterns of walls

and spaces
E,G 2 patterns of walls and

spaces that also include

laser cannons

Placement of the orbs is more diffi-
cult. The four orbs must not be in the
path of any laser, on or off the small
viewscreen, or they will be destroyed.
To determine where you want each
orb, multiply the vertical coordinate
by 70, add the horizontal coordinate,
and place the result in the DATA line
immediately following the screen
DATA line. This should be done with
each of the four orbs for each screen.

Below is an example of a custo-
mized first screen. Line 6000 is the
screen data, and line 6010 is the place-
ment data for the four orbs.

The only way to test your Arena
and make sure that everything is
working right is to RUN the game. If
you want to test a higher level, change
L = 0 in line 1070. L is the current level
minus one. So L = 7 would start you
out at level 8.

Now you should have enough to
get started. Have fun creating your
own Arenas.

HANDY USR
ROUTINES

Machine language power from BASIC

by ERNIE NEGUS

A collection of short but powerful USR machine language
routines that can he usefully plugged into your your
BASIC programs for any Atari computer Antic Disk
subscrihers l-MI-li 't):(!SHR(:Al!..I.ST" caul follow the
instructions in the article.

BASIC'S USR command lets you use speedy, memory-
efficient machine language subroutines from the comfort
of BASIC. Although these subroutines are tricky to type,
they let your BASIC programs access a wider variety of
functions, run faster and occupy less memory.

Simply put, machine code is a series of numbers stored
in memory. Each number stands for an instruction to the
computer Once you have the address of this code, the
USR function lets you run it from BASIC.

Machine code can be stored in several ways. Here, the
code is stored in character strings. We can now use BASIC'S
ADR function to find the beginning address of the
character string, and put this value into our USR call.

Since the computer interprets each character as a
machine code instruction, a single mistyped character
could cause your computer to lock up when you RUN
the program.

You must type in each character string exactly as it
appears, checking each line with TYPO II. Refer to the
Special Atari Character charts in the Antic listings sec-
tion if you need additional help.

Also, please note that you only need to type the dot-
matrix listing printouts marked with TYPO II codes. The
typeset example lines below each listing simply indicate
how these listings should be called up in these demonstra-
tions or in your own BASIC programs.

All USR calls have the general form: X = USR(z, pi, p2,
p3) where z is the decimal address of the machine
language routine, and pi, p2 and p3 are input values
(parameters) which the machine language routine will use.
While some USR calls do not need parameters, others de-
mand several. Any parameters you use must be numbers
between 0 and 65,535.

Here are some short USR routines which use machine
language to manipulate bits, perform multiple PEEKs and
POKES, evaluate Boolean expressions, and even play
music.

Let's examine our USR routines and see how they work:

15 ANS = USR(BBYT,pl,p2,p3,p4,p5,p6,p7,p8)

This routine converts binary numbers to decimal. In
our example, the rtiysterious-looking character string is
the machine language subroutine. The ADR function
determines the decimal address of the subroutine. This
address is stored in the variable BBYT Our final result will
be stored in ANS.

We'll use this routine to convert 00001111 to decimal:

First, type in the machine language string as shown
in line 10.

ANTIC, The Atari Resource

the toolbox

Now, type:

15 ANS = USR(BBYT,0,0,0,0,1,1,1,1)
17 PRINT ANS

When you RUN this demonstration, ANS will be equal
to 15, the decimal equivalent of 00001111.

USR routines which do not return values to your BASIC
program, such as MPOK, must also be equated to a BASIC
variable. Programmers often call these "dummy" variables
because they aren't used in any calculations, but are re-
quired by BASIC syntax rules.

RB 28 DPEK=flDR c"hhnihnGsi«Enaaiosiri*")

25 ANS = USR(DPEK,<address>)

This routine performs a double PEEK at any given
decimal address. Its BASIC equivalent is:

ANS = PEEK (<address>) + PEEK (<address+l>) * 256

Please note that items within angle brackets, such as
<address>, tell yOu what type of data the USR routine re-
quires. If you wanted to perform a double PEEK at address
1536, for example, you would type:

25 ANS = USR(DPEK,1536)

UE 38 MPOK=ftDH fhShTK

♦hhlBGHEH*"3

35 DUMMY=USR(MPOK,<address>,<bytel>,
<byte2> . . . )

MPOK will POKE any number of bytes into successive
memory locations, beginning at the specified decimal
address.

GU 48 DPOK=ftDR t"h52JhnDhauB»h7l'Jhr

45 DUMMY= USR(DPOK,<address>,<wordl>,
<word2>. . .)

DPOK works just like MPOK, except DPOK will POKE
any number of words into successive memory locations.

DG 58 HI = ADR("hh|!Sihin»:tI]*"J

55 ANS = USR(HI,<word>)

HI returns the high byte of any word. Its BASIC
equivalent is:ANS = INT(WORD/256)

RN 68 LOU=ADRC"hhh:ii]v;iI]*"]

65 ANS = USR(LOW,<word>)

LOW returns the low byte of any word. Its BASIC
equivalent is:

ANS=WORD-INT(WORD/256)*256

nn 78 BAND=flDRC"hSEErKnrii^^lIEIO'»^EEnn]E*"i

75 ANS = USR(BAND,pl,p2,p3. . .)

BAND performs a logical 'AND" on the bits of any
number of parameters. BAND can be used to separate
missiles and test the direction bits of the joystick ports.

FU 88 BOR = flDRC"hS£|wn[£I!]h-.[rEI!]h-.Eea!I^*-'']

85 ANS = USR(BOR,pl,p2,p3. . .)

BOR performs a logical "OR" on the bits of any number
of parameters. BOR can be used to set bits and alter display
list options.

10 98 BKOR = ADRt"h3]*:C£IBhE[in!]hEfeiXIIS*"l

95 ANS = USR(BXOR,pl,p2,p3. . .)

BXOR performs a logical "Exclusive OR" on the bits
of any number of parameters. The routine can be used
to control blinking characters and flashing colors.

LO 188 BROT=nDRC"hhnS^h;OQ'*?IID-n2hh[9Hann5^

105 ANS = USR(BROT,<address>,<direction>,<carry>)

BROT will rotate the bits of a byte in RAM. In line 75,
<address> is the decimal address of this byte, <direction>,
is the direction of rotation (use 0 for right rotation, 1 for
left rotation), and <carry> initializes the carry bit. ANS
will contain the carry condition after the rotation.

BROT can be used to rotate characters and players, and
convert decimal numbers to binary numbers.

This routine lets the computer play simple tunes from
data stored in MUSDAT$. Each note in MUSDATS is
represented by two bytes. The first byte of each pair is
the pitch value of the note. Consult your BASIC reference
manual for appropriate pitch values. The second byte is
the duration of the note, in jiffies.

Whole notes require approximately 60 jiffies, quarter
notes use approximately 15 jiffies. In our example,
MUSDATS holds the data for the last two bars of "Mary
Had A Little Lamb."

USR routines are easy to use and can breathe new life
into tired BASIC programs.

IMPROVED
PRINTED
LISTINGS

Spaces between Atari special
cliaracters will make Antic
program listings easier than
ever to type correctly.

See the new instructions for
Typing Antic Program Listings
in June's Software Library sec-
tion.

Antic's improved custom
printing program is written in
ACTION! by Michael Fleisch-
mann, a regular contributor
and a computer engineer at
Hill Air Force Bace in Utah.

bonus same

Release a mine by pressing the joy-
stick button. You can have up to four
mines on the i^oard at one time. To
retrieve an unused mine, touch it. The
mines become available again after
destroying an enemy. Naturally,
higher levels mean tougher
opposition.

HOW IT WORKS

Type in Listing 1 and .SAVE a copy
before you compile and RUN it.

Now let's look at some of the
game's more interesting ACTION!
procedures.

DRAW7 directly manipulates the
screen bytes to PLOT a point in the
specified color. It's considerably faster
than the built-in Atari PLOT function.

FASTDRAW is a high speed tech-
nique to put a high resolution picture
on the screen. It does direct byte
manipulation of the screen with no
math involved, so it is considerably
faster than even DRAW7. The value
of each byte that makes up the pic-
ture is stored in a byte army, and the
width, height, x and y coordinates
must be passed to the procedure.

The picture itself is generated using
Drawpic from Artworx. Drawpic
turns the picture you design on the
screen into BASIC DATA statements,
which can be listed to disk; the for-
mat can then be modified to fit into
an ACTION! program.

MOVEIT moves the player/missile
shape defined by byte array SHAPE
and player nimiber WHICH to the
specified position on the screen.

BOARDDRAW draws the initial
board. It uses FASTDRAW and the
byte array BLK to put the squares
with letter A on the board.

TESTCOL tests for collisions be-
tween the various players by sampling
the hardware collision registers. It
waits for a whole screen to be drawn,
then transfers the contents of the col-
lision registers to temporary locations
in RAM. The collision registers are
then cleared. Checking for collisions

is actually done by looking at the tem-
porary locations.

LLOC performs the same function
as LOCATE, but much fasten

GOTBUMPED processes the col-
lisions of the enemy players and a
mine. The explosion sounds and
flashing of the obliterated player are
handled by repeated calls to this pro-
cedure. It also removes the enemy
player from the board and positions
is back in its original corner.

MUNCH detects collisions between
your player and the energy pellets. It
also keeps the sound going and erases
the eaten pellet.

CHANGEDIR decides whether to
change the direction of an enemy
player It also checks to see if the
player can move in the indicated
direction. This procedure is only
called when the player is in an
intersection.

SMARTS determines whether the
enemy players are in an intersection.

OUCH is called if your player is
caught by an enemy.

CHASE calls SMARTS for each
layer, and moves the player if it hasn't
been destroyed by a mine.

MO'VEMAN reads the joystick and
moves your player It checks to see if
you can move in the direction you
want. If not, then you continue in the
direction you are traveling. Thus, you
can push the stick in the desired direc-
tion before you get to an intersection
and then move in that direction when
you hit the intersection.

FADER 1 1

Enhanced dot-by-dot picture dissolves!

by PATRICK L. DELL'ERA

Last month, we published Patrick
Dell'Era's reworking of Philip Price's
"Picture Painter." We now present
Patrick's Fader II, based upon the
popular dot-by-dot picture dissolve
program by Joseph Grande that Antic
printed in the September 1984 graph-
ics issue.

The original Fader was written in
the BASM language, which is now
often hard to find. Patrick has
disassembled the object code into full
MAC/65 source code, and re-written
it with several improvements in-
cluding a special modification pro-
gram in BASIC. -ANTIC ED

THE LISTINGS

There are three listings. Listing 1,
FADERII.BAS, is the main program. It
is written in BASIC and creates a
machine language binary file on your
disk called AUTORUN.SYS.

Listing 2, FADERMOD.BAS, is a
BASIC program which can be used to
modify certain of the elements in
AUTORUN.SYS. Listing 3, FADERII.
ASM, is the assembly language source
code and need not be typed in. It is
included for machine language pro-
grammers who may wish to study and
further modify the program.

Type in Listing 1 and check it

This is an enlwiicement oft/w po/ni-
lar "I'eicli'r ' 'program ll.>at a

original program crealed a dot-by-
dot "lapse-dissolve" ejjevt on Micro
Painter files. Fader II now works on
Micro Illustrator pictures as well. ITje
program is complete in this issue —
including source code. It will work-
on all Atari annpulcrs with iSK and
disk drive.

especially carefully with TYPO II.
Make sure you haven't skipped any
lines. TYPO II can't check for that.
SAVE a copy of the program. When
you RUN Fader II, it will read all of
those DATA statements (they are the
machine code) and then prompt you
to ready your disk and press
[RETURN].

Place a fresh, formatted disk in your
drive containing DOS 2. OS and two
or more picture files. Press [RETURN] ,
and a file named AUTORUN.SYS will
be written to your disk. Now, boot the
disk and the slide show will begin.

SLIDE SHOW II

Unlike the original program, Fader II
can handle both uncompressed and
compressed Graphics 7+ picture files.
This means you can have any com-

bination of Micro Painter or Micro
Illustrator files on the same disk.
(Micro Illustrator software comes with
the KoalaPad, the Atari Touch Tablet
and other widely used graphics
products.)

So that Fader II can tell the dif-
ference between the file types, you
must use a .PIC extender on your
compressed files. The Micro Painter
files should have a .?IC extender
(where ? designates any number or
letter other than P).

Fader II will cycle through each
picture creating a screen pixel
dissolve. When it reaches the last file,
it will begin again with the first. As
with the original program, you may
skip the pause between pictures by
pressing [START].

In Fader II, after a picture fades in,
it may be held indefinitely on the
screen by pressing [OPTION] . In this
way, one may take a good look at a
particularly fetching piece of art, or
gracefully change the disk without
racing the clock. If you have DOS on
your disk, pressing [SELECT] will take
you to it.

Fader II does not sit in the DURSYS
area of memory, so a Binary Load can

be done on it from DOS without
creating a MEM.SAV file. It will run
with or without a cartridge installed.

FADER II MODIFICATION

Although Fader II has an automatic
pausing rate, the modification pro-
gram, FADERMOD.BAS, will allow
you to change the length of time the
picture is left on the screen — as well
as the drive that the pictures aire
loaded from. This allows quite an ef-
fective display for Ramdisk owners
who load their pictures into the
simulated 128K disk and designate it
as the load drive.

Type in Listing 2, again checking it
with TYPO II and SAVEing a copy
When RUN, it will ask for the file
name (i.e. AUTORUN.SYS, FADERII.
EXE, etc.). It then uses NOTE and

POINT to read the appropriate vari-
ables. Each time the [OPTION] key is
pressed, the drive number is in-
cremented by 1. If it reaches 5, it rolls
back to 1.

The pause rate is modified by press-
ing [SELECT]. Each time [SELECT] is
pressed, the pause time is increased
by 4.27 seconds until it reaches (255*
4.27). It then becomes 0. If the minus
key [-] is pressed, the pause time will
be reduced with each press of
[SELECT]. Pressing any other key puts
it back into the increment mode.

When your variables are set to your
satisfaction, press [START] to save the
changes to your program. It is impor-
tant that the same disk Fader II is read
from should be the disk to which the
changes are written. Otherwise, an in-
nocent bystander on another disk

could be modified, surely causing its
demise.

LISTING 3

As mentioned above, Listing 3 is the
MAC/65 assembly source code. It was
created with the MAC/65 Assembler
Editor by Optimized Systems Soft-
ware, Ultra Disassembler by Adven-
ture International, and OmniMon by
CDY Consulting. Without these three
excellent programming tools, the
above code could not have been re-
created and modified.

TYPING SPECIAL

Shown below are the Atari Special Characters as printed in Antic listings— and the keys you must type in order
to get them. Boxes are drawn around the normal video characters here so you can see their positions more accurately,
these boxes do not appear in the printed listings.

Whenever the CTRL key (CONTROL on XL models) or SHIFT key is used, hold it down while you press the
next keys. Whenever the ESC key is used, press and release it before typing the next keys.

Turn on inverse video by pressing the Atari logo key JR. once. Turn it off by pressing a second time. (XL
models use the Reverse Video Mode Key Ql instead.)

Sometimes it's not easy to tell apart the following characters, shown here in both normal and inverse video.

HOW TO USE TYPO II

Type in TYPO U and SAVE a copy to disk or cassette.

Type GOTO 32000 and follow TYPO II onscreen instructions. If the resulting two-letter line codes are not ex-
actly the same as those in the magazine, you mistyped something in that line.

To call back any line previously typed, type an asterisk [ * ] followed (without in-between spaces) by the line number,
then press [RETURN]. When the complete line appears at the top of the screen, press [RETURN] again. This is also
the way you use TYPO II to proofread itself.

To LIST your program, press [BREAK] and type LIST. To return to TYPO II, type GOTO 32OO9.

To remove TYPO II from your program, type LIST "D:FILENAME",0,31999 [RETURN] (Cassette owneis LIST "C:).
Type NEW, then ENTER "D:FILENAME" [RETURN] (Cassette— ENTER "C:). Your program is now in memory without
TYPO II and you can SAVE or LIST it to disk or cassette.

Owners of the BASIC XL cartridge from O.S.S. type SET 5,0 and SET 12,0 before using TYPO II.

Reviewed by Harvey Bernstein

The marriage between hit movies and
computer software has been a rocky
one in the past. Games based on the
cinema have rarely been commer-
cially or artistically successful. That's
usually because the game is produced
as a rush-job to capitalize on the
motion picture's success. Until now,
that is. . .

Ghostbusters from Activision, is
the first adaptation to capture both the
feel and the theme of the movie on
which it is based. For those one or
two Antic readers who haven't seen
the movie, I'll explain.

Supernatural phenomena (referred
to in the game as PK levels) in YOUR
town are on the rise and ghosts are
everywhere. As the owner of the local
Ghostbuster franchise, it is up to you
to sweep the streets for mobile ghosts
(Roamers), clean all haunted buildings
of their inhabitants (Slimers), and
finally face down the dreaded Marsh-
mallow Monstrosity at the Temple of
Zuul. Succeed, and fame and fortune
are yours. Fail, and bankruptcy awaits.

Of course, no ghostbusters worth
their salt can go into business without
the proper equipment, and you have
the option to buy Image Intensifiers,
PK Energy Detectors, Ghost Traps,
Bait, etc.

As a new franchisee, the bank sup-
plies you with S 10,000 to start. But
as you progress and earn more money,
you can buy more sophisticated
equipment. You can win at Ghost-
busters by finishing the game with
more money than you started. But
sneaking two men into the Temple of
Zuul will earn you a substantial bonus.

This is Activision's first attempt at
a role-playing game, and while the
game is enjoyable, there is a flaw in
the design. At the end of a game, if
you are successful, you are given an
account number to correspond to
your name and winnings. It is up to
you to make a record of this number,
and enter it again next time you want
to play. Any deviation in the number
or in spelling your character's name,
and you must start over from the be-
ginning. It should have been a simple
matter to put in a save-game routine
to simplify matters.

And then there's the music. While
the adaptation of Ray Parker Jr.'s hit
is well done, it plays throughout the
game, over and over again. Since a
typical game may last 15-20 minutes,
a way to toggle the music off would
be more than appreciated. As it is, I've
taken to playing Ghostbusters with
the monitor sound turned all the way
down.

But these are just minor com-
plaints. Ghostbusters is most en-
joyable to play, and I hope it's a sign
of what Atari owners can expect from
Activision in the future.

Too many products being released
these days seem to be reha,shes of the
same tired arcade themes. So it gives

me great pleasure to announce that
Spy Vs. Spy is one of the most
original and clever games for Atari
computers yet.

The Black and White secret agents,
created by Cuban cartoonist Antonio
Prohias, have been one of the most
popular features in Mad Magazine
since i960. The game, with an ex-
cellent Atari adaptation by ace pro-
grammer Jim Nangano, not only re-
mains faithful to the cartoons, but is
challenging and great fun to play.

As the White spy, you race the clock
and your opponent Black (controll-
ed by either another player or the
computer) to find 5 items hidden

within an embassy. Once you acquire
the briefcase, secret plans, key,
passport and money, you must find
your way through a maze of rooms
to the exit leading to the airport.

But that's not all! During play, you
and your opponent leave traps for
each other — bombs, electrified water,
guns with strings attached to the trig-
ger and so forth. Setting off one of
these booby-traps puts you out of
commission for several valuable
seconds, giving your opponent the
edge.

Of course, as a well-armed spy, you
have an arsenal of remedies at your
disposal. So the umbrella neutralizes
the electrified water, the scissors saves
you from the gun with the string, etc.

One of the most unique features of

Spy vs. Spy is a technique First Star

White can be seen in the top half, and
Black in the bottom, allowing each
player to see what the other is up to.
When a player enters a room already
occupied, the action shifts to one half
of the screen for a winner-take-all
brawl.

I cannot recommend this game
highly enough. The graphics and
animation exploit all the possibilities
of the Atari. And with several levels
of play, Spy vs. Spy should provide
loads of fun for both novices and ex-
perienced gamesters.

Reviewed by Andy Barton

The MAC/65 Toolkit is an impressive
collection of some 67 macros
(assembly language subroutines) for
use with the MAC/65 Assembler
Editor. These macros greatly en-
chance the speed and ease of
assembly language programming for
both the novice and the experienced
programmer.

The Toolkit's macro calls mimic
many BASIC and assembly language
commands. This makes an assembly
language program almost as easy as
a BASIC program to write and debug.

The macros are grouped into three
libraries (files). The first library is a
collection of utility routines for
graphics, math, I/O and program
control.

The second library offers 11 macros
for setting up single line resolution
Player/Missile graphics, moving the
players and missiles with a vertical
blank interrupt, and detecting
collisions.

The third library offers a VBI
routine for vertical, horizontal, and
diagonal fine scrolling over a large

screen display using the joystick.

The Toolkit allows assembly lan-
guage beginners to focus on overall
programming without having to
develop complicated routines. An
elementary understanding (or handy
reference book) of assembly language
is necessary for using this kit. It is also
desirable to have a moderate famili-
arity with Atari's P/M graphics. The
user's manual is clear and concise, but
it's not as helpful for newcomers as
I would have liked.

The P/M graphics library needs a
macro for joystick input. Writing one
might be a good first project for the
user. The joystick routine from the
scroll library, while not directly
transferable, is a good starting point.

The libraries use fairly large blocks
of memory. The utility library itself
occupies slightly over six pages (about
1 1/2K). The P/M graphics library oc-
cupies a little less then two pages and
the scroll library just over one page
of memory. If memory space be-
comes a problem, you can, with a bit
of effort, go through the specific
libraries deleting any unused macro
before final assembly.

This learning game might have some
trouble competing with the latest
Infocom adventure. However, U. S.
Adventure — by Antic contributing
editor Jerry White — could work very
well in a history class, or be enjoyed
by a youthful history buff. You've got
to know your facts to succeed.

First you've got to know the order
in which each state entered the union.
There's a help key to give you clues,
but each clue takes away points. You
must move from state 1 to state 2, etc.,

by using directional signals which ap-
pear on the screen in the form of a
compass.

After you've correctly guessed the
state, you choose your next move
from an Options Menu. From this
menu you can choose Time Travel,
Take Event, Review Map (here's where
you get clues to the order of states),
and several other less-used options.

Take Event and Time Travel test
your knowledge of American history
some more. You choose Take Event
only after you have correctly chosen
the next state's entrance. You're given
several historical events and must
weed out ones that may be bogus.
Watch out for those! They can
drastically alter your points.

Then you move to Time Travel to
guess the year that the particular event
took place. Time Travel offers nice
computer sound and graphics as you
appear to be looking through a long
colorful tunnel. Years, 1776, 1821,
etc. , pass by and you control when to
stop, advance, or go backward. "Vt)u've
got to correctly guess the date of an
event with as little time travel as pos-
sible. (I hadn't read the instructions
all the way through and got very in-
trigued with making those years go
backward and forward through this
tunnel ranging in hues from yellows
to purples to blues. Well, I paid for the
fun with my score!)

This learning game is full of in-
teresting facts and proves to be a good
history lesson. However, the instruc-
tions are not easy to follow and there
are a lot of them. Getting from state
to state seemed more convoluted than
it had to be. I also found a spelling er-
ror: Massachesettes. That's really
unacceptable in any piece of software,
and especially in a learning game.

However, none of this is enough to
turn thumbs down on the whole pro-
gram. Young history buffs will enjoy
U. S. Adventure and the game could
certainly add a spark to any classroom
history lesson.

50 MISSION CRUSH

50 Mission Crush puts you in the
pilot's seat of a B-17 heavy bomber in
World War II. Your goal is to survive
50 missions from an Air Force base in
England against 23 targets in Nazi-
occupied Europe.

Your opposition includes enemy
fighters and flak guns, weather, your
own inexperience, and the random
number generator. This role-playing
game lets you share the feelings of a
real pilot — relief when a "milk run"
target is selected by the computer,
dismay when yet another fighter
shoots holes in your damaged
bomber, frustration when the target
is protected by clouds, anxiety as you
pray your fuel will last until you return
to England.

You control the movement of the
bomber as well as functions such as
dropping bombs, changing altitude,
and fighting fires. You direct the fire
of your machine guns when fighters
appear And you watch helplessly as
puffs of flak appear around the plane.
The crew members become more
effective at their jobs as they gain
experience. Games and crews can be
stored on disk for continuation at
another time.

This is not a visually exciting game.
The few animation sequences used
are very simple. The game moves
slowly in spots, possibly because it is
written in BASIC. Combat sound
effects are good, but more sound
features would add to the game. The
game is easy to learn and play. A
typical mission takes 5 to 10 minutes
of real time.

The strength of 50 Mission Crush
lies in its detailed simulation of com-

bat results. Damage accrues gradually
and realistically. Consumption of fuel
and ammunition require constant
decision-making. I took more damage
from flak than from enemy fighters,
in contrast to the historical reality.

Unfortunately, there is not much of
a learning curve with 50 Mission
Crush. Random events play a larger
role in your fate than do skill and
practice. This is a good operational-
level war game, but don't expect a lot
of exciting air combat action.

When Muse Software introduced
Castle Wolfenstein for the Apple in
1981, it quickly shot to the top of the
charts and remained there as one of
the most popular games for any
microcomputer The Atari translation
was remarkably faithful to the Apple,
right down to the lousy sound and
black-white-green-purple graphics.

Now we have the sequel. Beyond
Castle Wolfenstein, and while there
have been some minor improve-
ments, the game play doesn't provide
nearly as much depth as the docu-
mentation suggests.

The scenario in the follow-up is dif-
ferent, yet similar enough to the
original to allow the same spare
graphics. As an allied intelligence
agent, you must penetrate Der
Fuhrer's bunker, a 3-level maze of
rooms. Hidden in a closet on the first
level is a time bomb, which you must
find and then set outside Hitler's
office, two levels below, after which
you must retrace your steps out before
the whole place goes up.

As in the original, each room is

swarming with unfriendly guards.
You have no uniform to allow you ac-
cess, but you do have numbered
passes. When you enter a room, the
guard demands to see your pass. If
you show the wrong one, you will
probably be arrested, but you do have
money to bribe the guards.

Once you find the correct pass for
a level, it works with every guard on
that level, so the game becomes a lot
easier The chests of the previous
game have been replaced by closets,
some of which are locked, requiring
the talents of a safecracker

There are some improvements over
the original, most notably the speech
synthesis used for the guards. With a

little practice, you can recognize their
grunts as actual German words. Also,
if you accidently walk into a wall, you
don't get the filling-rattling routine
that accomanied Castle Wolfenstein.

Now for the bad news. The game
promises more than it delivers in
strategy. For example, while I found
keys in several closets, after playing 3
games in progressively difficult levels,
I found nothing to use them on. Also,
there is a toolkit which the documen-
tation says can be used to disable the
alarm system. Not only do I still not
know how to disable the alarm, but
I've yet to figure out why I would
want to.

Once you know which passes to
use, you can breeze through the game
with only mapping needed. It's this
sameness and ease that keeps me from
going back to play Beyond Castle
Wolfenstein again and again. Not to
mention that it takes so long to load
that it recalls fond memories of my
old 410 recorder 0

THE

"IMPOSSIBLE"!

® they claimed!

$149.95

Backup almost any disk currently availabie (even heavily protected programs) with an UNMODIFIED disk drivel

Works with ANY disk drive!

ATARI

$149.95

PURPOSE: The "IMPOSSIBLE" was developed in response to the estimated half million disk drive users that own a drive other than the Atari 810 (Indus, Per-
com, Trak, Rona, Astra, etc.) that wish to BACK UP their protected software. Due to a radically new technology developed by Computer SofhA/ore Ser-
vices, modification to your disk drive has been eliminated! The advantages are obvious! Drive warranties are not violated, the chance accidental
damage has been eliminated, etc., etc.

OPERATION: The "IMPOSSIBLE"! consists of a disk program (unprotected so you can make as many backups as you wish) and a 4K STATIC RAM pack
which is inserted intoyour computer (no soldering!)The"IMPOSSIBLE"! will reodyour program disk and then re-write it in an unprotected format! You may
make additional backup copies using a sector copier or even regular DOS! Because your backup copy no longer has BAD SECTORS or EXOTIC FORIVIATS,
the program data can now be manipuiated into DOS compatable files (even double densit/l), transfered to cassette, etc. (with the aid of our Satellite
programs!) No user programming knowledge required. A few programs require logical thinking.
FEATURES: 1. Backup protected disks 5. AFSD-Automatic FUZZY Sector Discriminator

2. Handles most MULTI-LOAD programs 6. Expands computer memory to 52K usable

3. Mokes DOS flies (with Satellite option) 7. Simple NO SOLDER installation

4. Up to 90K data input capable 8. Satellite expandable

PROJECTED SATELLITES: A "COMPACTOR" program which will convert your program into DOS compatable files (double density compatable!) for the
storage of several programs on one disk. A "COLUMN 80" program for Word Proccessing, etc. It allows 80 columns on the screen! The "XL-MATE" will allow
programs made with your 400/800 "IMPOSSIBLE"! to nowplay on your XL Computer! The METAMORPHOSES II program will allow you to convert your pro-
tected CASSETTES into disk DOS files and vice-vorsa. All satellite programs must be used with inconjunction with The "IMPOSSIBLE"!
REQUIREMENTS: The "IMPOSSIBLE" diskette, the 4K STATIC RAM pock, a 400 or 800 computer (please specify!) with 48K and "B" Rom's. NOTE! The very old
ATARI computers were shipped with "A" Rom's which hod some serious "Bugs". Even if you don't own an "IMPOSSIBLE,"you should upgrade to "B" Rom's
(simple to Install!) We have them available at a very inexpensive price. CALL US! "XL" version available soon!

NOT A PIRATING TOOL: We at C.S.S. did not design The "IMPOSSIBLE"! to put Software Manufactures out-of-business overnight! Nearly all of our products
have been "ripped-off ' by industry parasite who have little or no ability to develop a product of their own so we can sympathize with their dilemma. Ail
C.S.S. products have built-in safe guards which prohibit their use for flagrant pirating. The "IMPOSSIBLE"! is no exception! While The "IMPOSSIBLE"! back-
up the most heavily protected programs, it also checks to see that the 4K STATIC RAM pack is installed before allowing the backup copy to
execute!

EXAMPLES: The "IMPOSSIBLE"! has been tested on 300 of the most pop-
ular and heavily protected programs we could find. With nearly 4000
programs for Atari, we DO NOT guarantee that it will backup ol! pro-
grams in the pasf-present-and future! We will supply updates atS6 each
(non-profit!) if and when necessary. Programs we hove successfully
backed up Include: Blue Max, Visi-coi, Archon, Muie, File Manager 800
+, Syn Cole, Syn File, One on One, 7 Cities of Gold, Super Bunny, Load
Runner, Drol, and Gumboil just to name a few!
